A centrifugal pump is used to pump water at 77ºF from a reservoir whose surface is 20 ft above the centerline of the pump inlet. The Pipe System consists of 67.5 ft of PVC pipe with a 1.2 in ID and negligible average internal roughness height. The length of the pipe from the bottom of the lower tank to the pump inlet is 12 ft. There are several minor losses in the pipe: an acute edge entry (KL = 0.5),...
1. You are designing a pumping station and have been asked to size and select a pump from 2 models. The system step is as follows: the discharge line is a 21-inch diameter PVC pipe with an assumed constant friction factor of f 0.014. The length of the piping is 2300 ft with an elevation gain of 40 ft and an exit loss (K-1.0).. The pump station is located near sea level and the temperature of the flow stream is...
You need to pump water at 20 C from an open reservoir at flow rate of 1.4 x 10^-3 m3/s through a pipe with an inside diameter of 0.03m, using a centrifugal pump having an (NPSH)aq =2.5 m and the equivalent length on the suction side is 3m. There are several minor losses: four standar 90 flanged elbows, and fully open flanged globe valve, fully open flanged gate valve, and the Entrance. What is the the maximum distance above the...
Problem 4 The pumping system shown in the figure below to deliver 3 cfs of 60°F water. The total elevation difference between is 84 ft. The suction line is a 6-inch diameter, 300-ft long cast-iron pipe. The discharge line is 6-inch diameter in an 860-ft long plastic pipe. The suction inlet for the pump is 20 ft above the reservoir. The atmospheric pressure is 14.70 psia. The required NPSH is 7.0 ft. Minor losses include entrance: k, = 0.5, open...
30 points You need to pump water at 20 °c from an open reservoir at flow rate of 14 x 10-3 m?s through a pipe with an inside diameter of 0.03 m, using a centrifugal pump having an (NPSH)req = 2.5 m and the equivalent length on the suction side is 3 m. There are several minor losses: four standard 900 flanged elbows, and fully open flanged globe valve, fully open flanged gate valve, and the entrance. What is the...
If a pump with the characteristic curve shown in the accompanying graph (Figure 2) is used to pump water from the lower to the upper tank (water flows from Tank 2 to Tank 1 in this question) shown in Figure 1. Use information provided in Figure 1 and assume that diameter of pipe AB is 600 mm (DAB 600 ) and diameter of pipe BC is 300 mm DBc 300 mm) a. Find the operation point of this systenm b....
Q4: The pump is used to deliver of water from a river to a storage reservoir. The four pipes are connected in series of Inverse L shape which means the first pipe in vertical direction and others in horizontal direction. The first pipe in vertical position of 500m length of 150 mm diameter cast iron pipe, the second pipe is bend at 90' with a radius of 0.75m, the third pipe in horizontal direction of 100m length of 160mm diameter...
6. Determine the setting of a centrifugal pump, given that flow rate = 2.4 m/min; diameter of intake pipe = 160 mm; entrance losses = one velocity head in suction pipe; required NPSH = 42 kPa; water temperature = 30°C N D1, D2 : inlet and outlet diameters of impeller (rotor) b : impeller width 0,6 : inlet and outlet impeller vane angles (degrees) : speed of rotation of impeller (and its driver) in rpm V, V :tangential and radial...
The system below uses a centrifugal pump to circulate water at 19°C, having a vapor pressure of 2320 Pa, from a low reservoir to a higher one through a cast iron pipe with a diameter of 35 cm and surface roughness of 0.25 mm. The minor head losses upstream of the pump are represented by EK1 = 0,6 and downstream by & K2 = 7. After several months of usage, it is noticed that the installation is noisy and consumes...
A pump transports water from Tank 1 to Tank 2 through a constant-diameter piping system as shown below (not to scale). The flow rate is controlled by two gate valves, the gate valve I controls the main pipeline, while the gate valve II controls the loop line from T-joint A to T-joint B. All pipes are galvanized steel pipe of diameter D = 4 in. It has a total length of Li2= 620 ft from tank 1 to tank 2....
